Miniature rose plant named ‘Poulpar123’

ABSTRACT

A new garden rose plant of the Miniature class which has abundant, yellow flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical designation: Rosa hybrida.

Variety denomination: ‘Poulpar123’.

This application claims priority to Plant Breeder's Rights ApplicationNumber 2020/2267, which was filed at the Community Plant Variety RightsOffice in the European Union on Sep. 21, 2020, the contents of which arehereby incorporated by reference for all purposes.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of roseplant which originated from a controlled crossing between the femaleseed parent, an unnamed seedling, and the male pollen parent, also anunnamed seedling. Both of the parent varieties are non-patented.

The two parents were crossed during the summer of 2011 and the resultingseeds were planted in a controlled environment in Fredensborg, Denmark.The new variety, named ‘Poulpar123’, originated as a single seedlingfrom the stated cross.

The new variety may be distinguished from its male pollen parent andfemale seed parent primarily by the following characteristics. The malepollen parent plant has white flowers while the new variety has yellowflowers. The female seed parent plant yellow orange flowers while thenew variety has yellow flowers.

The objective of the hybridization of this rose variety was to create anew and distinct variety with unique qualities, such as:

-   -   1. Uniform and abundant yellow flowers;    -   2. Vigorous, but compact growth when propagated on its own        roots;    -   3. Exceptional disease resistance.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventor, anddistinguish ‘Poulpar123’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization during winter of 2011 andconducted evaluations on the resulting seedlings in a controlledenvironment in Fredensborg, Denmark. ‘Poulpar123’ was selected in thespring of 2012 by the inventor as a single plant from the progeny of theaforementioned hybridization.

Asexual reproduction of ‘Poulpar123’ by rooted cuttings was first doneby Mogens N. Olesen in the nursery in Fredensborg, Denmark in July,2012. This initial and other subsequent asexual propagations conductedin controlled environments have demonstrated that the characteristics of‘Poulpar123’ are true to type and are transmitted from one generation tothe next.

DESCRIPTION OF THE DRAWING

The accompanying color illustrations show as true as is reasonablypossible to obtain in color photographs of this type, the typicalcharacteristics of the buds, flowers, leaves, and stems, of‘Poulpar123’.

Specifically illustrated in FIG. 1 of the drawings are open flowers atvarious stages of development, flower petals detached showing receptacleand reproductive flower parts, and sepals detached.

Specifically illustrated in FIG. 2 of the drawings is a cluster offlower buds on the branch, leaves, bare stem, and juvenile bare stemwith juvenile leaves. Plants shown are 10 months of age.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulpar123’, as observed in itsgrowth in an open air container nursery in Odense Denmark. Observedplants are 10 months of age, and were grown on their own roots in 24 cmpots. Color references are made using The Royal Horticultural Society(London, England) Colour Chart, 2001, except where common terms of colorare used.

For a comparison, several physical characteristics of the rose variety‘Poulpar112’, U.S. Plant patent application Ser. No. 16/602,258 arecompared to ‘Poulpar123’ in Chart 1.
